Abstract (en)
[origin: EP0391485A1] The invention pertains to the production of high-purity fatty-acid lower-alkyl mono-esters which comprises a first transesterification step between glycerol fatty-acid esters and a lower alcohol, a separation step wherein the reaction product of the esterification step is separated into glycerol-rich and fatty-acid lower-alkyl mono-ester rich fractions, a second esterification step in which all glycerol and fatty-acid glycerolesters of the fatty-acid lower-alkyl mono-ester rich fraction are esterified to the corresponding fatty-acid triglycerolesters, and a recovery step wherein said fatty-acid lower-alkyl mono-esters are recovered.
